The Members Only Club

This is a fun (but highly unnecessary side quest) that you can partake in as soon as you get to Troia. To partake, you'll need to acquire 10,000 Gil before coming to Troia - once you have the money, head to the Pub. A lady near the entrance on your left will offer to sell you a Membership Pass for 10,000 Gil. Purchase the pass and then approach the man ahead who will ask you see it. Select it from the menu, go through the door and into the secret basement, where you can see a dance show! Not very exciting, not very useful... but an optional little event that you can watch if you so desire.
